Using it in background profiling mode is rather inefficient, as psyco
has to learn what to pseudo-JIT on every bzr invocation. It would be
better to do some profiling and psyco a few specific code paths that can
benefit from it, and where bzr spends a significant portion of its
running time.

If Rob and Martin support adding some psyco directives to bzr, this
would be a neat and very quick little project for you to pick up.
